キンバリー・ビレル — ケイティ・ボリネット の予想

Birrell has already beaten Volynets on this hard-court swing, recovering from a set down to win 2-6, 6-2, 7-5 on the way to her first tour title. Ranked 40 to Volynets’s 88, she followed with a 6-1, 6-1 win over Aoi Ito; her 4-6, 4-6 loss to Marie Bouzkova was no collapse.

+2.5 games suits a close match: it covers a Birrell win and a narrow Volynets victory. Birrell has had about ten days off, no reported injury, and says she moved on quickly after Seoul. Her work with Nicole Pratt adds continuity. Volynets’s Philadelphia title, Mertens comeback and two Wuhan qualifying wins are real positives, but the workload is substantial: 2h25 and nearly three hours in Beijing, then 2h17 against Osorio. She faces a fresher opponent after an early start.

Volynets led Birrell by a set in Seoul, then lost; against Mertens, she led by a break in the decider and still lost. Those swings leave room for a resurgence, but not enough to dismiss the cushion. The 21.5 total is a pass: frequent breaks make both a long match and sharp straight-set swings plausible. Birrell to win outright is tempting; the handicap better protects against a close loss.
